This invention deals with a wrinkle coating
composition and a process of manufacturing if.
In most .of the wrinkle coating compositions
used heretofore if bas been necessary to subject
the off and sometimes also the final composition
fo a cooking process in order fo obtain a wrinkle-
textured surface. This cooking step not only pro-
longs the process of manufacture, but also in-
creases the cost and requires additional care.
Moreover, the coatings prepared from the com-
positions used heretofore bave fo be dried by
forced means süch as by heating in an oven by
infra-red light or the like.
It is an object of this nvention fo provide
wrinkle coating compositions for the preparation
and application of which hardly any heating is
required.
It ls an object of th invention fo provide
wrnkle coating compositions which are air-dry-
ing.
If is an object of this invention fo provide
wrinkle coating compositions in which no heat
is required for the blendIng step, slnce the mix-
ing of the ingredients ls carried out at room tem-
perature.
If is another object of this invention to pro-
vide wrinkle coating compositions which dry fo
hard wrinkle-textured coatIngs af room tempera-
ture in a relatively short rime.
It Is still another object of this nventlon fo
provide wrinkle coating compositions whlch yield
coatngs having a gret hardness and a long serv-
ice lire.
These and other objects are accomplished, by
cold-blending a non-wrinkling varnIsh with raw
tung off.
If was quite unexpected and surprising fo find
that by merely mixing these materlals which per
se are non-wrinkllng, products are obtained which
dry withou any application of heat thereby form-
Ing coatings with a uniform wrinkle texture and
of great hardness. A process for the production
of wrinkle finishes bas thus been devised by this
invention which ls characterized by great sim-
plicity and low cost.
Quantifies ranging from 1 gallon fo 10 gallons
of non-wrlnkling varnish per 1 gallon of raw
tung off may be used. The higher the off con-
tent, the more pronounced the wrinkling texture.
The varnishes used for the compositions of my
invention comprise from 8 fo 12 gallons of oiticica
off, 100 pounds of phenol formaldetyde resIn,
from 1 to 3 pounds of a hardening material such
as litharge, red lead or the like, and from 12 fo. 20
gallons of thinner, such as xylol, toluol, solvent
naphtha, high fiash coal tut naphtha, hydrogen-

ated naphtha, petroleum r thinner or a mixture
of any of such thinners. In preparing the var-
nishes the resin and the off are first heated fo-
gerber fo approximately 450 ° F.; thereafter the
5 hardening substance is added and the mixture
heated fo a temlerature ranging from 490 ° fo
500 ° 1. This temperature is held until a tough
and hard pill is obtained on a glass plate, which
takes about from 30 minutes to one hour. The
10 mixture  then allowed to cool to 350 ° 1. when
the thinner is added. In spire of the use of
oiticica off, and in spire of the varnish being sub-
jected fo a cooking process, the final product ob-
tained is of the non-wrinkling type.
15 If a colored coating ls to be produced, the addi-
tion of a coloring laste is necessary. Such a
çaste preferably contains alproximately equal
amounts of filler and coloring marrer together
with a small quantity of non-wrinklng varnish
20 and with thinner material which is preferably a
highly volatile solvent.
The filler materials round particularly suit-
able are asbestine, silex, diatomaceous earth,
blanc fixe, or mixtures of these or other known
25 inorganic filler materials.
Coloring materials which bave been round op-
erative for the invention are the various grades
of carbon black, chrome yellow, chrome green,
Iron pigments, titanium oxide, iron blues, orga.nic
30 toners and the like.
The coating composition may be applied to the
article fo be provided with a wrinkle-textured
film by any method known in the art; brushing,
immersing and spraying, for instance, are satis-
35 factory. However, application by spraylng Is the
lreferred method.
In the following, a few examples for the new
coating compositions are given as preferred em-
bodiments of my invention. These examples are
40 by no means limitative but are fo serve merely
as illustration.
EXAMPLE I
43 A varnish was prepared by first heating a mix-
ture of 100 pounds of rosn-modified phenol form-
aldehyde resin and 10 gallons of oiticica oil to
approximately 450 ° 1. and then adding under
50 stlrring 2 pounds of litharge. This mixture was
then heated fo 500 ° 1. for about 45 minuteswhen
a pill thereof applied fo a glass plate and cooled
showed a tough and hard consistency. There-
after the batch was allowed fo cool fo approxi-
55 mately 350 ° F.; 5 gallons of xylol and 10 gallons
of toluol were then added: ..
